Prouducts 
Contant NH300 Portable Colorimeter
Product Comparison
1. Leading Humanity Design and Convenient Operation
Auto White and Black Calibration at Startup
Structure Design in line with Ergonomics
Easy-to-use Operation Interface
2. Stable Measurement Performance
The average fluctuation of △E is less than 0.07, actually more in 0.03~0.06.
Portable structure design which is more conductive to keeping the instrument stable when using.
3. Convenient and Fast Locating
Illumination locating is a fast, simple and convenient locating function which is the original function by 3nh.
4. PC Software—Realize More Function Expansion
3nh has the intellectual property of PC software. The corresponding software serial number and
password protection are configured in 3nh colorimeter.
Be able to perform color difference analysis, color difference cumulative analysis, chromaticity index, color sample database management, simulating object color, etc.
5. Advanced Power Management Design
3nh is the first enterprise using high capacity Li-ion battery in colorimeter.
3nh Li-ion battery can be repeatedly charged which will save cost. Meanwhile, it can measure more than
3000 times on one charge to ensure the stability of long time measurement.
